SLASHER.

Specification of Letters Patent.

Patented J an. 9, 1912.

Application filed July 21, 1910. Serial No. 573,099.

To all whom it my concern:

Be it known that I, Louis A. A'UMANN,

a citizen of the United States of America,

residing at Chicopee, in the county of 5 Hampden and State ofMassachusetts, have invented new and useful Improvements in Slashers, ofwhich the following is a specification.

This invention relates to improvements in Slashers for winding warpyarns on the beam-roll, and the object is to provide a structure bymeans of 'which the I warp threads are evenly laid on the loom-beamduring the winding operation. Frequently, the warp-threads, afterleaving the drying rolls, are crossed as they pass onto the loom or beamroll causing trouble when the beam- ,roll isput into :the loom, andduring the weaving operations, the threads are broken or cause troubleas they are drawn from the beam-roll.

A further object of the invention is to provide means for adjusting thewarpfi'xthreads so that they will all be properly ,5; guided duringtheir travel onto the beam- "i r ol-l; also to provide means for rigidlyfas- -{tening the individual cones or dents of the ;-='c omb-bar inplace.

In the drawings forming part of this application,-Figure l is a planview showing my improvements and the comb-bar pivotally mounted on atransversely arranged adjustable bar, with means for adjustably securingthe comb-bar at any angle of-adjustment, and-showing'a band or sheath ofthreads. F ig; .2 is a side elevation of Fig. illustrating the passageof the several .of warp-threads through the comb mooth-ing-bars andtension rolls. Fig. iorizontal, sectional view on the line 3; of, Fig.5. Fig.ft.-.i's a top plan view of ejcomb-bar illustrating the inclinedand angular'arrangement of the teeth and with the threads from theseveral bands or wheels separated. 'Fig. 5 is a vertical, sectional viewon the line 55 of Fig. 3, and

showing one of the teeth nearly full size. Fig. 6 is a side elevationalview of Fig. 4 illustrating the inclined pins or dents of the teeth, andthe threads from the several bands brought down into a horizontal planefor winding onto the beam-roll.

Referring to the drawings, a indicates a ortion of the main frame of themachine showing the loom-beam ,b; 0 the tenslonrolls: (Z thesmoothing-bars; 0 bands or sheaths of warp-threads that are to be woundonto the loonrbeam Z), the threads having been previously separated intoseveral horizontal planes as shown in '60 Fig. 2, by means of suitablebars (not shown) in the usual manner. The band of warp-threads as itleaves the splitting bars and travels toward the comb-bar f lies inseveral horizontal planes as indicated at e".

The object of this invent-ion is to change the plane .of the band ofwarp-threads from several horizontal planes to one horizontal plane inwhich the threads are positively placed, and is accomplished by means ofthe '70 teeth 9 of the bar f, and the smooth bars -(Z. The teeth arerigidly secured in said ba-r. These teeth, it will be noticed, stand atan angle to the line of travel of the -warpthreads, as shown in thefigures and they also stand at an oblique angle, or are inclined to, thehorizontal plane, as indicated in Figs. 4 and 6. The result of this-a'1' rangement of the teeth is to cause the warpthreads to engagethefront side of the teeth,

as indicated at it, of one of the teeth, and the rear side of theadjacent tooth, as indicated at i. r

By reason of the inclined and angular arrangement of the teeth 9 thethreads 6 will be positively and automatically separated before theypass under the smooth bars (Z by means of the teeth, as shown in Figs. 4and 6. These teeth cause each one of the threads of all of the bands toautomatically pass onto the beam-roll in a positively separated positionside by side in a straight line and without any dangerot one threadoverlapping or crossing another.

It will be noticed that the upper ends of v9.5 the teeth 9 are madepointed, as indicated at j. This construction permits the threads to bereadily separated one from the other. in getting the machine ready forthe winding operation.

It frequently happens that the width of the several bands is greaterthan the distance between the heads 6 of the beam-roll b, and in orderto overcome this objection, the comb-bar If is pivotally connected tothe adjustable bar is at the point m. One end of this bar is providedwith an arc-shaped member 0 having aslot p therein for receiving athumb-nut g by means of which the bar f may be locked in any suitable110 angle to the bar k, whereby the several bands or sheets ofwarp-threads will be bent out of their course of travel and broughtnearer to each other so that they will wind onto the beam-roll b.

As a means of bringing the band of warpt-hreads in perfect alinementwith the heads 6 of the beam-roll b the bar is is slidably mounted inthe side-plates 1" and s of the frame, and this bar is provided with athread on the rod projecting from one end, as indicated at z". udesignatesa wheel engaging this thread,.whereby the bar f may be movedtransversely. I

The lower ends of the teeth 9 are rigidly secured in the bar 7; whereas,it is the usual practice to yieldingly secure them in the bar, as bymeans of a closely coiled spring, the teeth being inserted between thecoils whereby when the coils of this spring are ti htened their angularadjustment may be e ected. This construction, I have found to beineffective for the purposes intended.

From this construction, it will be seen that the only means employed forpositively and automatically positioning the threads of the bands orsheets so that all will pass under the smoothing-bar d, is the comb-barf which is-provided with the oblique and 5 angularly arranged teeth '9.The comb-bar is located between the point where the several sheets ofthreads are separated at e and the smoothing bar d.

What I claim, is

1. In a slasher, a pin structure, the teeth of which are placed in aninclined and angular position to the line of travel of the warp-threadsto separate and arrange the said threads so that several horizontalplanes of them, as they approach the teeth, i are positively andautomatically brought amass];

the threads are drawn past thepin struc ture to the beam roll. 7

2. In a slasher, a beam roll, a comb-bar,

the teeth of which are rigidly secured thereto and arranged in anoblique and angular position to the line of travel of several horizontalbands of warp-threads, whereby said warp-threads are automaticallychanged from the several horizontal planes to one horizontal plane asthey engage the beamroll, and means for retaining the comb-bar at anangle to the line of travel of the threads.

3. Ina slasher, the combination with the 4:. In a slasher, a beam-roll,a comb .ele

ment for causing several horizontal bands 'of warp-threads to beautomatically and positively arranged into a single horizontal plane asthey are wound onto the beam-roll, said element comprising a series of.teeth arranged in parallel relation to each other and inclined to thehorizontal plane and angular to the line of travel, the front and rearedges-of the teeth being provided with a curved surface, and means foroperating the beam-roll.

5. A comb-bar for slasher machines, the thin flat teeth of which arearranged in an angular position with respect to the line of threadtravel and inclined po'sition to and rigidly secured in said bar.
